PS7219单片机显示的源程序

单片机串口通信模板，Keil工程打包，包括两种单片机8051和C8051F020. 有多机通信协议，数据格式为“起始码+本机地址+数据”，模板中已建立接收数据、命令处理、数据发送等流程，极大地方便了串口通信的开发。-Single-chip serial communication templates, Keil engineering package, including two single-chip 8051 and C8051F020. How machine communication protocols, data format for the

自己写的CH452的驱动，用keil C51写的-himself wrote the CH452 drive with the Keil C51 write

由8051组成的单片机系统通常情况下，P0口分时复用作为地址、数据总线，P2口提供A15-A8即高8位地址，P3口用作第二功能，只有P1口通常用作I/0口。P1口是8位准双向口，它的每一位都可独立地定义为输入或输出，因此既可作为8位的并行I/O口，也可作为8位的输入输出端。当工作在输入方式时，对应位的锁存器必须先置1,才能正确地读到引脚上的信号,否则,执行读引脚指令时,若对应位的锁存器的值为0，读的结果永远为0。-By 8051, composed of single-chip microcomputer system under normal circumstances, P0 timeshare I reuse as address, data bus, P2 I provide A15-A8 high eight address, P3 mouth for the second function, I usually only P1 for I/0 I. P1 I was eight quasi-two-way port, it can be independent of each and every defined as input or output, it can be used as 8-bit parallel I/O port, can also be used as 8-bit input and output side. When the work in the input, the corresponding bit latch must first buy one in order to correctly read the signal pin, or pin the implementation of reading instruction, if the corresponding bit latch the value of 0, Reading the results of Forever to 0.

本程序实现74HC165芯片的使用功能，在51单片机上实现-this program is to tell how to use 74hc165 on 51 single chip controlere

频率计的设计,单片机初学者必须程序,适用于proteus-Frequency of the design, single-chip microcomputer program for beginners to be applicable to proteus

很不错的频率计的设计，希望大家多多指教-Cymometer very good design, I hope everyone exhibitions

红外遥控控制步进电机源代码，对步进电机开发也许有些帮助-Infrared remote control of stepper motor source code, the development of the stepper motor may be of some assistance
